Don't standardize (as has been wrongly done with the W3C Semantic Web standards) anything before it has become practice (ChrisWelty) (2YBM)

Standards must be short and stable (not as e.g. OWL 2 vs. OWL 1) (MartinHepp) (2YBN)

Even a clear specification (as in the case of rdfs:range) can mean that adopters can get it wrong. People need to be able to adopt a standard even if they only understand a fraction of the spec. Positive examples: SQL, HTTP (which are long standards) (MartinHepp) (2YBO)
